can't find my pre 96 Aero service cd.

my 96 97 Ford Aero service DVD does no show a schematic for the air bag system, only one shown is for the Ranger which is different.

they are avail online and ebay

Chilton and Haynes manuals do not list the Aero air bag schematic.

the crash sensors are a 2 circuit system.
1 closed circuit for air bag controller testing that the sensor is still there
1 open system that closes during a crash

system requires 2 crash sensors to close in crash to set off the explosive bag.

my guess from your air bag code #41 is that one of the continuous closed test circuits is broken wire or open from poor connection.
